To all whom it may concern: The shafts O extend to the rear, for use as Be it known that I, OHARLEs H. KNAPP, of handles in manipulating the machine. Mansfield, in the county of Tioga and State of To the rear thill-bar, c, is attached an arm, Pennsylvania, have invented a new and Imi, which extends downward and through a proved Machine for Preparing the Soil for slot in a plate, k, attached on bar A, and the 55 Crops, of which the following is a full, clear, arm has notches for engaging plate 7., in order and exact description. to hold the shafts in position either raised or My improved machine is intended to form lowered. This arrangementregulates the depth raised ridges for receiving tobacco or other to which the scrapers g act, and also allows IQ plants, and it is constructed to raise and roll the whole weight of the machine to be thrown 60 two ridges at once. I also combine with it a upon the rollers when the handles are raised, gage or marker, and construct the machine so as to facilitate turning and allow the maso that the rows or ridges can be made of any chine to be moved upon roads. required depth and at any suitable distance To each end of the cross-bar A an arm, m, apart, as herein described and claimed. is jointed, and at the outer ends of these arms 6 Reference is to be had to the accompanying are attached markers at, for the purpose of drawings, forming a part of this specification, gaging or marking arow at either side of the in which similar letters of reference indicatev machine, as may be required, at the same time corresponding parts in all the figures. that two rows or ridges are being raised and Figure 1 is a front perspective view of my rolled. 7 improved machine. Fig.2isatransverse sec- At the center of bar A is hung a handtion, showing the adjustment for regulating lever, t, and rods 8 s connect this lever with the depth of the ridge. Figs. 3 and 4. are dearms-m, for simultaneous movement of both tail views, showing the attachment of the rollarms when lever t is moved. The arrangeers to the main frame. ment is such that the two arms stand up from The frame of the machine consists of acrossthe ground at an angle of about forty-five debar, A, upon which are two brackets, 13 B, on grees when the lever is in the middle position, which the thill-bars-c c are attached.

The levert Sc to the main bar A is made by hinged joints at engages a notched cross-bar, c, in its middle I) on the forward edge of the bar, which allows position, and is pressed thereto by a springthe shafts to be raised and lowered. These rod, a. hinged joints may be ofany suitable character. In the operation of the machine it is to be 35 DD are the rollers, sustained in brackets d, drawn forward by horse-power, and the two whichareconnected upon movableslide-blocks knives'g at each side serve to raise a ridge, 6, attached at the ends of the main cross-bar the top of which is rolled and leveled by the A.
